8668: FIL-R is a background character in WALL•E. FIL-R is a tanker truck bot aboard the Axiom. FIL-R appears from a trapdoor on the floor when the probe ship has docked in the Axiom. When FIL-R has arrived it starts immediately to fuel the probe ship. Two arm-like bots, 077 and 229, also appear from trapdoors at the same time as FIL-R does.
- Its name is a pun on "filler".
